Hawley's campaign on Wednesday said he raised close to $1 million between
October and the end of December. Attorney General Hawley now has about $1.2 million in cash to spend on a bid to unseat McCaskill.

McCaskill's campaign says she raised close to $2.9 million in the same time period. She now has more than $9 million in cash on hand to spend on a run for a third term.

That leaves Hawley more than $7 million behind McCaskill in fundraising for what's likely to be one of the most hotly contested races in the nation.
